MOUNT FOB FLEXIBLE SYNCHRONIZED GUNS.

Application filed April 18, 1822; Serial No. 555,422.

To all whom it may concern:

Be it known that we, HERBERT 0. Russian and. CHARLES LEIGH PAULUs, citizens of the United States, residing, respectively, at Detroit and Dayton, in the counties of Wayne and Montgomery and States of Michigan and Ohio, have invented certain new and useful Improvements in Mounts for Flexible Synchronized Guns, of which the following is a specification.

This invention relates to mounts for flexible synchronized guns, the object of the present invention being to produce a gun mount which will admit of the gun being adjusted in azimuth, at the same time maintaining the operation of the gun in synchronism with the propeller.

With the above and other objects in view, the invention consists in the novel construction, combination and arrangement herein fully described, illustrated and claimed.

In the accompanying drawings:

Figure 1 is a top plan view, partly 1n section. of our device;

Figure 2 is a side ele ltlOIl of our device with certain portions shown in dotted lines.

Referring to the drawings, the trunnions 1 of the gun 1 are supported by a turntable 2 mounted for rotation in suitable bearings rovided on a stationary base 3. Mounted 1n the base is a diametrically slidable bar 4 which is hollow to receive the end portion of an impulse cable 5 leading to the stationary impulse generator.

A bell crank lever 6 is mounted on a horizontal pivot 7 on hearing members 8 carried by the bar 4, andhas one arm attached to the cable 5 and its other arm swivelled, with slight play at 9 to the lower end of a vertical movable connecting rod 10 mounted for vertical reciprocatory movement directly in line with the axis of movement of the turntable 3.

A second bell crank lever 11 is mounted on a horizontal pivot 12 on the turntable and has one arm swivelled to the upper end of motor operating cable 13 which extends to the trigger motor 13 mounted on the side of the gun. A long cam surface 14 on the turntable works in contact with a roller 15 mounted on a vertical stud or shaft 16. adacent to and on one end of the slidable bar 4.

Owing to the center location of the rod 10,

when the gun is swung to the right or to the left, impulses will be transmitted from the cable 5 to the cable 13 through the medium of the bell crank levers 6 and 11 and the connecting rod 10 regardless of the portion armed by the gun. As the turntable supporting the gun turns 1n its bearings, the cam 14 forces the roller outwardly and thus imparts a thrust to the bar 4. The result of this motion will be a shifting of the pivot of the bell crank lever 6. This in turn efl'ects an adjustment of the impulse cable 5 and causes the firing impulses to come at a lower point on the impulse cam of the generator. Due to the play in the swivel 9., the pivot of the bell crank lever 6 may approach the rod 10 or recede therefrom without altering in any way the vertical thrust of the connecting rod 10 or interfering with its movement. A clamping member 17 is provided for use in securing the turntable at any desired adjusted position of the gun.

What we claim is:

1. A mount for a flexible synchronizing gun, embodying a stationary base, a turntable on said base between said gun and its impulse generator, a gun having trunnions in hearings on said turntable, a trigger mOtOr on the gun, and means for operating said trigger motor from a stationary impulse generator while permitting rotation of the turntable, said means comprising an impulse cable, a trigger motor operating cable, and connecting means between said cable including a connecting rod the longitudinal axis of which is coincident with the axis of rotation of the turntable.

2. A mount for a flexible synchronizing gun, embodying a stationary-base, a turntable on said base between said gun and its impulse generator,a gun having trunnions in mg a connecting rod the lon'itudinal axis hearings on said turnable, a trigger motor of which'is coincident with t e axis of ro- 10 on the gun, and means for operating said tation of the turntable, and levers connecting trigger motor from a stationary impulse gensaid cables with said connectin rod.
